Boswall questions
Do you take on hotel work around Boswall?
Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.
I let a flat near Edinburgh Waverley station. Can you help?
Yes, rental work is part of what we do. You can email us at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before any work starts.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Do you cover Boswall?
Yes. We’re based in Crawley and work across South East England, London and Scotland, and that includes Boswall.
Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Are you fully insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Can you fix a reseal that hasn’t worked?
Yes. We will take all the sealant out, look for why it failed and reseal it properly.
Remedial sealant in Boswall, done properly
A joint that keeps failing normally has a reason. Movement, the wrong product or a leak from somewhere else will beat any new bead. We look for the cause before we reseal. Typical jobs include torn expansion joints and sealant peeling off a dusty or damp surface, across failed movement joints, leaking tray & enclosure joints and expansion joints.
Boswall is in one of Scotland’s four big cities, where many tenement bathrooms were fitted into rooms that weren’t built for them. Rooms like that are often small and slow to dry out, which is hard on sealant and grout.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

The process
We keep the work tidy and contained to the area we are working on, so you can carry on as normal. The job generally takes a few hours for most joints, depending on how much old sealant has to come out. Parking in city streets around Boswall can be tight or controlled, so it helps to know about permits or nearby bays. If you are in a flat, let us know how we get in at the street door.
- We start by checking the joint for movement, leaks and the reason it failed.
- Every layer of old sealant is cut and cleaned out.
- The joint is cleaned, treated for mould and left to dry.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- We tool the joint and tell you about anything else that needs attention.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Let us know about earlier repairs to the joints
- Let us know about stairs, lifts or work at height
Ask for a quote

Related advice
DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

What else we do in Boswall
Remedial sealant around Boswall
Boswall is close to the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, which wears sealant and grout out faster than in a quiet home. Edinburgh has a lot of tenement flats, in the Old and New Towns and well beyond, and in a tenement, a leaking seal can reach the neighbours below.
In the older streets around Granton Congregational Church, older homes can move a little, which is hard on rigid grout and tired sealant. Letting a property close to Edinburgh Waverley station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Quotes for remedial sealant in Boswall
Every job gets its own quote. This is what makes a difference:
- The size of the job
- How many rooms, windows or areas are involved
- How much old sealant there is and how hard it is to remove
- Which sealant suits the joint
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
Asking for a quote
Photos by email are helpful but not essential. Please mention:
- Where the property is
- What the problem is, such as mould, gaps, leaks or cracking

Honest limits
We will always be straight with you, so here’s what sealant cannot fix:
- Cracks in the fitting rather than the joint
- Water damage behind tiles that needs a tiler
- A leaking trap, valve or supply pipe
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly.
Joints and surfaces we work on
- Mouldy bath & shower sealant
- Botched or over-sealed joints
- Leaking tray & enclosure joints
- Expansion joints
- Failed movement joints
- Shrunken worktop sealant
Common problems we fix in Boswall
All sealant wears out eventually. Mould grows into the silicone, the surface hardens and the bead shrinks, especially in damp, poorly aired rooms. Then the only fix is removal and a new bead.
These are the problems we are asked about most:
- Floor or wall movement joints that have failed
- Gaps opening along the back of the worktop
- Mould trapped under a layer of silicone
- Beads that never stuck properly
Managing a site like Broughton High School? Then we reseal washrooms and kitchens in schools and businesses as well as homes.

Surface by surface
Windows & doors
A frame that keeps leaking may not be the mastic. If the frame joint isn’t the cause, we will say so.
Leaking trays & enclosures
If the tray is cracked, or the leak is from the valve or waste, sealant won’t fix it. We’ll tell you what we find.
